What's preventing Africa from developing economically...

And Chinese.

I 2009 the Unite Nations have sent best Holla Forums posters on the special expedition to Africa.
Expedition have taken 3 years. Total cost was 45 gazilions of zimbabwe dollars. Effect was the 300 page long report, that contributed Africas poverty to "niggers".

all this plus climate change is threatening African farms and the fact that most african nations are basically forced to pay off billions in debt to the west which outnumbers all of the aid they receive.

I would agree with most people here, and blame it on neo-imperialism.
IIRC, Gaddafi was killed (in part) because Libya's currency was beginning to unite African finance, economically threatening the French presence, who then whined for an invasion.

also:

A carefully engineered system of international debt, subsidies, tariffs, and corruption which efficiently extracts surplus value from the workers and ensures it goes into the hands of capitalists rather than being reinvested into the economy.

Capitalism.

You're giving trans-national organizations too much credit.

Wow. Seychelles is really socialist?

no, user is right. post-colonial nations are intentionally loaded up with debt by the IMF and World Bank.

nah, it would be nuked by now
